Rock Hog's DTH Hammers


In September of 2009, Rock Hog introduced its new "HP" Series DTH Hammers.  The results have been rock shattering, to say the least.  In countless numbers of field test comparisons, in a wide array of rock formations, Rock Hog's "HP" DTH Hammers have yet to be equaled. 

Each "HP" Hammer is factory tested to ensure that you receive the same Rock Hog product reliability that you have come to expect, while adding improved performance to your drilling.

The "HP" models are available in 3.5", 4", 4.5", 5", 5.5", 6", 6.5" & 8" diameters and are commonly used in  
water well, quarry, open pit mining, underground mining, construction, blasting, environmental and oil and gas industries.
